Some individuals diagnosed with PDD-NOS under the old manual would be identified as individuals with SCD under DSM-5, according to the APA. DSM-5 also added a new category called social communication disorder (SCD) to diagnose individuals who have verbal and nonverbal communication impairments but lack other attributes associated with autism. DSM-5, eliminates these subgroups, instead establishing a more limited range of criteria for a diagnosis of ASD that is designed to encompass individuals who previously would have fallen into one of the subgroups. “This study raises a concern that a medical provider diagnosing a child under the new guidelines won’t find the child to be on the autism spectrum, when the same child under the old criteria might have been diagnosed with ASD,” says Kulage.ĭSM-IV-TR included three distinct subgroups under the broad definition of ASD: autistic disorder (AD), Asperger’s disorder, and pervasive development disorder–not otherwise specified (PDD-NOS). The study found a statistically significant decrease in ASD diagnosis of 31 percent using the new manual, DSM-5, compared with the number of cases of ASD that would have been identified under the previous version of the manual, DSM-IV-TR. Kulage, MA, MPH, director of the Office of Scholarship and Research Development at Columbia Nursing, conducted a systematic literature review and meta-analysis to determine the effect of changes to the Diagnostic and Statistical Manual of Mental Disorders (DSM), the APA’s classification tool for psychiatric conditions, on diagnosis of individuals with ASD. The guidelines, released in May 2013 and the first major update to psychiatric diagnosis criteria in almost two decades, may leave thousands of developmentally delayed children each year without the ASD diagnosis they need to qualify for social services, medical benefits, and educational support.Ī team led by Kristine M. Problems of organization and planning hamper independence.(NEW YORK, NY, February 24, 2014) – New diagnosis guidelines for autism spectrum disorder (ASD) issued by the American Psychiatric Association (APA) may reduce by almost one third the total number of people being diagnosed, according to research from Columbia University School of Nursing published in the February 2014 issue of the Journal of Autism and Developmental Disorders. Inflexibility of behaviour causes significant interference with functioning in one or more contexts. For example, a person who is able to speak in full sentences and engages in communication but whose to-and-fro conversation with others fails, and whose attempts to make friends are odd and typically unsuccessful. May appear to have decreased interest in social interactions. Difficulty initiating social interactions, and clear examples of atypical or unsuccessful responses to social overtures of others. Without supports in place, deficits in social communication cause noticeable impairments. Distress and/or difficulty changing focus or action. Inflexibility of behaviour, difficulty coping with change, or other restricted/repetitive behaviours appear frequently enough to be obvious to the casual observer and interfere with functioning in a variety of contexts. For example, a person who speaks simple sentences, whose interaction is limited to narrow special interests, and who has markedly odd nonverbal communication. Marked deficits in verbal and nonverbal social communication skills social impairments apparent even with supports in place limited initiation of social interactions and reduced or abnormal responses to social overtures from others. Great distress/difficulty changing focus or action. Inflexibility of behaviour, extreme difficulty coping with change, or other restricted/repetitive behaviours, markedly interfere with functioning in all spheres. For example, a person with few words of intelligible speech who rarely initiates interaction and, when he or she does, makes unusual approaches to meet needs only and responds to only very direct social approaches. Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning, very limited initiation of social interactions, and minimal response to social overtures from others. Requiring very substantial support (Level 3) Restricted, Repetitive Behaviours (Criterion B)
